IMPROVEMENT IN LAMP-COLLARS.

Specification forming part of Letters Patent No. 155,925, dated October 13, 1874: application filed l September 4, 1872.

To all whom it may concern:

Be it known that I, WILLIAM B. GARRING- TON, of the city of New York, in the county of New York and State of New York, havejnvented certain new and useful Improvements in Lamp-Collars; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to a new and improved lamp-collar, its object being to prevent the heat ofthe fla-me from being transmitted to the body of the lamp and its contents, and also to allow the lamp to be filled without removing the cap; and, further, to collect and return to the lamp any oil that may be carried over by the wick, and prevent it from finding its way down the sides of the lamp and defaein g the same.

My invention consists in constructing the collar with two concentric tubes, with an airspace between them, projecting downward into the lamp, the upper edge of the outer tube attached to that portion ot' the collar which is fastened to the lamp, the inner tube eX- tending upward and attached to an air-chamber, said chamber being provided with apertures for filling, and returning the drip or waste oil which may find its way to the outside of the lamp from the wick or otherwise, as hereinafter fully described.

In the drawings, Figure l represents asectional view of my improved lamp-collar, and Fig. 2 a top view of the same. Fig. 3 represents a perspective view of the lamp-collar, showing spring-catch. v

A represents the outer tube attached to the annular collar B in any suitable manner. In practice, however, it will be found more convenient to form the tube and collar B in one piece, by spinning or otherwise. Within the tube A, and connected to it at its lower end, is another tube, G, of such size as to leave an air-space between its outer side and the inside of tube A. Said tube extends upward, and is attached to an annular air-ehamber, I). The

upper side of said air-chamber is slightly concave or dished, and is provided with an aperture, E, threaded, as shown, for the reception of the screw-cap, which carries the wick-tube. At one side of the aperture E I form an aperture, F, through the top of the air-chamber D, and directly opposite this aperture, on the other side of the aperture E, I form a small aperture, c. .The aperture F is for the pur pose of filling the lamp, the small aperture Gr serving to return any oil which may collect upon the top of the air-chamberD, and prevent it from running down the sides of the lamp. Just below the top of the air-chamber, and inside of the same, I arrange an annular slide,

H, perforated to correspond with the apertures F and G. The object of said slide is to close the aperture F after the lamp is filled. To the said slideIattach a spring, I, which serves as a handle, by which the slide may be moved, and also as a catch for holding the slide in position when the aperture F is closed. The catch I operates to hold the slide H by its downward tension, and its shoulder locking down into and against the side of the orifice F when the slide His closed. When the slide is to be moved, the spring is lifted so as to release its shoulder from the edge of the oriiice F, when it may be shifted so as to open the aperture F. rlhe aperture G remains open when the aperture F is closed, to allow the oil to return to the lamp, if any should be carried over by the wick.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

In a lamp-collar, the combination of the outer tube A and inner tube C, the latter extending above the former, and communicating with a chamber, D, provided with apertures F and G, for filling and returning the drip or waste to the lamp, as herein described. In testimony that I claim the foregoing as my own invention, I affix my signature in J. H. GARRINGVTON,l OHAnLEs NETTLETON.
